The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday warned that multiple nation-state actors are exploiting security flaws in Fortinet FortiOS SSL-VPN and Zoho ManageEngine ServiceDesk Plus to gain unauthorized access and establish persistence on compromised systems. "Nation-state advanced persistent threat (APT) actors exploited CVE-2022-47966 to gain unauthorized access to a public-facing application (Zoho ManageEngine ServiceDesk Plus), establish persistence, and move laterally through the network," according to a joint alert published by the agency, alongside Federal Bureau of Investigation (FBI), and Cyber National Mission Force (CNMF). The identities of the threat groups behind the attacks have not been disclosed, although the U.S. Cyber Command (USCYBERCOM) hinted at the involvement of Iranian nation-state crews. The findings are based on an incident response engagement conducted by CISA at nn unnamed aeronautical sector organization f...

Proof-of-concept (PoC) exploit code has been made available for a recently disclosed and patched critical flaw impacting VMware Aria Operations for Networks (formerly vRealize Network Insight). The flaw, tracked as CVE-2023-34039, is rated 9.8 out of a maximum of 10 for severity and has been described as a case of authentication bypass due to a lack of unique cryptographic key generation. "A malicious actor with network access to Aria Operations for Networks could bypass SSH authentication to gain access to the Aria Operations for Networks CLI," VMware said earlier this week. Summoning Team's Sina Kheirkhah, who published the PoC following an analysis of the patch released by VMware, said the root cause can be traced back to a bash script containing a method named refresh_ssh_keys(), which is responsible for overwriting the current SSH keys for the support and ubuntu users in the authorized_keys file. "There is SSH authentication in place; however, VMware forgot to r...

  Fortinet has released patches to address a critical security flaw in its FortiGate firewalls that could be abused by a threat actor to achieve remote code execution. The vulnerability, tracked as  CVE-2023-27997 , is "reachable pre-authentication, on every SSL VPN appliance," Lexfo Security researcher Charles Fol, who discovered and reported the flaw alongside Dany Bach,  said  in a tweet over the weekend. Details about the security flaw are currently withheld and Fortinet is yet to release an advisory, although the network security company is expected to publish more details in the coming days. French cybersecurity company Olympe Cyberdefense, in an independent alert,  said  the issue has been patched in versions 6.2.15, 6.4.13, 7.0.12, and 7.2.5. "The flaw would allow a hostile agent to interfere via the VPN, even if the MFA is activated," the firm noted. With Fortinet flaws  emerging  as a  lucrative   attack vector  for threat...
